BACKGROUND OF THE INVENTION

1. Field of the Art

The present invention relates to a dye intermediate, a dye and a thermaltransfer sheet. More particularly, it is concerned with an intermediatecapable of providing a dye excellent in the coloring density, sharpness,light fastness, safety, etc., a dye and a thermal transfer sheetexcellent in the above-described properties.

2. Background Art

Various thermal transfer processes are known in the art. Among them, asublimation transfer process has been practiced which comprisessupporting a sublimable dye as a recording agent on a substrate sheet,such as paper, to form a thermal transfer sheet, putting the thermaltransfer sheet on a transfer material dyeable with a sublimable dye, forexample, a polyester woven fabric, and applying a thermal energy in apattern form from the back surface of the thermal transfer sheet totransfer the sublimable dye to the transfer material.

In recent years, a proposal has been made on a process wherein variousfull color images are formed on paper or a plastic film through the useof the above-described sublimation type or thermal transfer system. Inthis case, a thermal head of a printer is used as heating means, and anumber of color dots of three or four colors are transferred to thetransfer material, thereby reproducing a full color image of an originalby means of the multicolor dots.

Since the color material used is a dye, the image thus formed is veryclear and highly transparent, so that the resultant image is excellentin the reproducibility and gradation and the quality of the image is thesame as that of an image formed by the conventional offset printing andgravure printing. In this method, it is possible to form an image havinga high quality comparable to a full color photographic image.

The most important problem in the thermal transfer process resides inthe color density, sharpness and light fastness of the formed image, andno dye which could have sufficiently solved these problems are known inthe art.

The thermal transfer sheet of the present invention is characterized inthat use is made of the above-described particular dyes. The otherconstitution may be the same as that in the conventional thermaltransfer sheet.

The substrate sheet containing the above-described dye used in thethermal transfer sheet of the present invention may be any known onehaving a heat resistance and a strength to some extent. Examples of thesubstrate sheet include paper having a thickness in the range of fromabout 0.5 to 50 μm, preferably in the range of from about 3 to 10 μm,various types of converted paper, a polyester film, a polystyrene film,a polypropylene film, a polysulfone film, a polycarbonate film, anaramid film, a polyvinyl alcohol film and cellophane. A polyester filmis particularly preferred.

The dye supporting layer provided on the surface of the above-describedsubstrate sheet comprises a layer produced by supporting on thesubstrate sheet a dye selected from those represented by the generalformula (I) by means of an arbitrary resin.

The binder resin for supporting the above-described dye may be anyconventional one, and preferred examples thereof include celluloseresins such as ethyl cellulose, hydroxyethyl cellulose, ethylhydroxycellulose, hydroxypropyl cellulose, methyl cellulose, cellulose acetateand cellulose acetate butyrate, and vinyl resins such as polyvinylalcohol, polyvinyl acetate, polyvinyl butyral, polyvinyl acetoacetal,polyvinyl pyrrolidone and polyacrylamide. Among them, polyvinyl butyraland polyvinyl acetal are particularly preferred from the viewpoint ofthe heat resistance and the migration of a dye.

The dye supporting layer of the thermal transfer sheet of the presentinvention is basically comprised of the above-described material and, ifnecessary, additionally contains various additives known in the art.

The above-described dye supporting layer is preferably formed by addingthe above-described dye, binder resin and optional components to asuitable solvent to dissolve or disperse the individual components inthe solvent to prepare a coating solution or an ink for the formation ofa supporting layer, coating the coating solution or ink on the substratesheet and drying the resultant coating.

The thickness of the supporting layer thus formed is in the range offrom about 0.2 to 5.0 μm, preferably in the range of from about 0.4 to2.0 μm. The content of the dye in the supporting layer is preferably 5to 70% by weight, still preferably 10 to 60% by weight based on theweight of the supporting layer.

Although the thermal transfer sheet of the present invention, as such,is sufficiently useful for a thermal transfer application, it is alsopossible to further provide a surface tack eliminating layer, that is, arelease layer, on the surface of the dye supporting layer. The provisionof such a layer enables the tack adhesion of the thermal transfer sheetto the transfer material to be prevented during the thermal transfer, sothat an image having a better density can be formed through the use of ahigher thermal transfer temperature.

Regarding the release layer, a considerable effect can be attained bymerely adhering an antitack inorganic powder. Further, for example, itis also possible to select a highly releasable resin, such as a siliconepolymer, an acrylic polymer or a fluorinated polymer, and to provide arelease layer of the selected resin having a thickness in the range offrom 0.01 to 5 μm, preferably in the range of from 0.05 to 2 μm.

The inorganic powder or releasable polymer can exhibit a sufficienteffect also when it is incorporated in the dye supporting layer.

Further, a heat resistant layer may be additionally provided on the backsurface of the thermal transfer sheet for the purpose of preventing anadverse effect of heat from a thermal head.

The transfer material used for forming an image through the use of theabove-described thermal transfer sheet may be any one as far as therecording face has a capability of accepting the above-described dye.When the transfer material is paper, a metal, glass, a synthetic resinor other material incapable of accepting the dye, a dye accepting layermay be formed on one surface such a material.

Means for applying a thermal energy used in the thermal transfer throughthe use of the thermal transfer sheet according to the present inventionand the recording material may be any means known in the art. Forexample, a desired object can be sufficiently attained by applying athermal energy of about 5 to 100 mJ/mm² through the control of arecording time by means of a recording device, for example, a thermalprinter (for example, a video printer VY-100 manufactured by Hitachi,Limited).

The present invention will now be described in more detail withreference to the following Example and Comparative Example. In theExamples and Comparative Examples, "parts" is by weight unless otherwisespecified.
